DETACHABLE SAW-HANDLE.

SPECIFICATION forming part of Letters Patent N o. 673,276, dated April 30, 1901.

Application filed February 14, 190].. Serial No. 47.346. (No model.)

To all whom, t may concern.-

Be it known that I, GoRNIELoUs J. MAO- CLA1N,acitizen of the United States, residing at Hatton, in the county of Wood and State of Ohio, have invented new and useful Improvements in Detachable Saw-Handles, of which the following is a specification.

My invention relatesto vimprovements in that class of saw-handles which are constructed with a view of adapting them to be readily connected to and disconnected from sawblades, and has for its general object to provide a detachable saw-handle which, in addition to being susceptible of ready application to and removalfrom asaW-blade, is calculated to lend rigidity to the blade and lessen the liability of the same being twisted or broken` in practice.

With the foregoing in mind the invention will be fully understood from the following description and claims when `taken in connection with the accompanying drawings, in which- Figurel is a broken elevation of my improved handle connected to a saw-blade. Fig. 2 is an enlarged horizontal section taken in the plane indicated by the broken line 2 2 of Fig. 1 looking in the direction indicated- A is a saw-blade having an aperture a adf jacent to its end.

Bis the body or main portion of myimproved handle, which is preferably of malleable iron, and C is the grasp Yof the handle, which is preferably of wood. The body or main portion B in the preferred embodiment of the invention is formed of a single piece of metal bentfso as to comprise an eye or-loop b for the reception of the reduced portion ofthe grasp O and parallel plates c d, the former of which is provided at itsforward end with a portion c/ of increased thickness, in which is formed a longitudinally-disposed threaded socket c2.

Fig. etis a transverse section taken,

This socket is designed to receive the threaded shank of a tongue e, bent, as shown, and adapted to be passed through the aperture a, of the blade and engage said blade after the manner best illustrated in Fig. 2. The said independent tongue is advantageous because it may be formed of steel, While the body B is formed of malleable iron or other cheap metal, and also because it is adapted to be adjusted to accommodate itself to apertures loc-ated at different distances from the ends of saw-blades.

The plate d of body B is provided with an outwardly-pressed or offset longitudinal por tionf, in which is formed a longitudinal slot g. Said offset or outwardly-pressed portion ,f-is designed to receive a coiled spring h,

which is interposed between it and the plate c and bears at one end against a shoulder 7l at the outer end of the portion f. At its opposite end the spring h bears against the end of a slidable bolt J, which it serves to normally hold in the position shown in Fig. 2T that is to say, extended beyond the end of the plated, so as to rest at the opposite side of a saw-blade with reference to the portion of the tongue e adjacent to the plate c. Bolt J is provided with a finger-piece j, through the medium of which it may be readily retracted against the action of spring h to draw it out of engagement with the saw-blade and permit of the handle being disconnected from said blade.

D is a gage-plate which is slotted at la to accommodate the spring h and is also slotted, as indicated by Z, to receive the transverse bolts m, which connect the plates c and d of the body B. By reason of this construction it will be observed that the plate D, which has a square forward end n, adapted to bear against the end of the sa w-blade, may be readily adjusted and adj ustably fixed to adapt the handle for application to different saws that is to say, saw-blades the apertures of which are arranged at different distances from the ends thereof.

I do not desire to be understood as confining myself to an adjustable tongue, as it might be formed integral with the plate c of body B Without departing from the scope of my claims.

`In order to remove my improved handle from a saw-blade, it is simply necessary to retract the bolt J until it clears the end of the blade, When by moving the handle to a position at an angle to the blade the tongue e may be readily Withdrawn from the aperture of said blade. To connect the handle to the blade, itis sim ply necessary to reverse the operation described-JL'. e., to insert or pass the bent portion of the tongue through the aperture of the blade While the handle is held at an angle to the blade and then move the handle into a position in alinement with the blade and release the bolt J and permit it to assume a position at the oppositeside of the blade With respect to the portion of the tongue adjacent to the plate c. When the'handle is thus Vapplied, it will be seen thatthe blade bears at one end against the `gage-.plate D and rests between the bolt J and a portionv of the tongue e adjacent to plate c. By virtue ofthis rigidity and strength is lent the blade and liability of the same being Vbroken or twisted in practice is reduced to a minimum.

It will be appreciated from the foregoing that my improved handle is simple and durable in construction, and in addition to being susceptible of ready and secure connection toa-nd disconnection from a ASaw-blade is calculated to add to the strength and period of usefulness of the saw-blade. I haveentered into la' detail description of the present ernbedirnent of my invention in Order t0 impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as con lining myself to such specific construction and arrangement of parts, as such changes 0r medifieatious may be Iliade in practice as fairly fall Within the seope of my invention. f

Having .described my invention, what I claim, and desire to `s eeureloy Letters Patent, 1s-

1. A detachable saw-handle comprising a body provided with a tongue adapted to rest at one sideof a saw-blade 21nd terminating in a bent portion adapted lto be passed through au. aperture in the ,blade .and engage the opposite side thereof, and a spring-banked bolt arranged in the body and adapted, in its nerr'nal position, to .rest at the opposite side of the blade, with reference tothe main portion of the tongue.

2. A detachable saw-handle comprising `a body provided with a tongue adaptedV to rest at one side of a saw-blade and terminating in a bent portion adapted to be passed through an aperture in the blade and engage the opposite side thereof, a spring-backed bolt arranged in the body and adapted, in its normal position, to rest at the opposite side of the blade, with reference to the main portion of the tongue, and a gage adjustably fixed in the body and adapted to bear against the end of the saw-blade.

3. A detachable saw-handle comprising a metallic body having the loop or eye to receive the grasp, a side portion terminating in a tongue provided with abent portion, a side portion or plate having an offset and a slot therein, b olts connecting the side plates or portions, a bolt .having a finger-piece extending through the slot in vone side plate of the body, .a spring occupying the offset in said side plate, and backing the bolt, and a gage-plate interposed between the side plates or portionsofthe body and having slots receiving the connecting-bolts thereof.

4, A detachable `saw-handle comprising a body having a threaded socket, a :threaded tongue adjustable in said socket andadapted t0 reet at oneside of '(vSaW-bladeand terminatingin a bent portion adapted lto-:be passed thnough an aperture'iu the `blade and engage the opposite Side thereof, andmeans carried by the -body and arranged .to rest ,atfthe opposite side of the blade with reference to the main portion ,ef the tongue.

5 A detachable .Saw-handle comprising a body having a threaded socket, a threaded tongue adjustable in. saidsocket and adapted to rest at one side of a saw-blade and terminating -in a leent .portion adapted-to be passed through an aperture in the :blade and engage theopposite .Side thereof, means carried by the bedy and .arranged yto rest at the eppe- Site side of the blade with reference t0 the main .portion of the tongue, and a gage adjustahly fxediu thelbody andadapted to abut against the end ofthe saw.blade.

In testimony whereof I nave hereunto set my band in presence of two subscribing witnesses., l
